Research Objectives

A robust dataset was collected as Hurricane Frances made landfall on the eastern coast of Florida on 5 September 2004. This dataset included dual-Doppler coverage of a convective cell in an outer rainband. Using this dataset, the objectives of this research are:

To characterize the kinematic structure of the convective cell and compare it to current conceptual models.

Examine changes in the kinematic structure of the convective cell as it crosses the coastline.

Conceptual Models/Previous Research

 Powell (1990)

Hence and Houze (2008) 

Hurricane Frances (2004)

Hurricane Frances SMART-R Deployment

SR-1 deployed at Merritt Island Regional Airport

SR-2 deployed at the Space Coast Regional Airport in Titusville.

Both radars sampled the northern portions of Frances, including the convective outer rainband.
